Application filed May 24, 1916.

' To all whom z't may concern.'

Be it known that I, GooDnrcH Q. Lewis, a citizen of the United States,residing at Wheaton, in the county of Du Page and State of Illinois,have invented a certain new and useful Improvement in Railway-CarDraft-Rigging, of which the following is a full, clearconcise, and exactdescription,v

reference being had to the accompanying drawings, forming a part of thisspecification.

This invention relates to improvements in railway car draft rigging.

One object of the invention is to provide a draft rigging of highcapacity of the tandem type so arranged that the shock absorbing unitsmay be inserted and removed without disturbing the yoke and draw bar.

Another object of the invention is to provide a draft rigging of thetandem type wherein is employed a horizontal yoke arranged to remainstationary under buff and having upper and lower, front and intermediatestops extending'between the sills and bracing the latter.

The invention furthermore consists in the improvements in the partsanddevices and in the novel combinations of the parts and devices hereinshown, described and forming the subject matter of claims.-

In the drawing forming a part of this specification, Figure 1 is avertical longitudinal sectional View of-a draft rigging embodying myimprovements. Fig. 2 1s a horizontal sectional view of the structureillustrated in Fig. 1 and'taken on the line 2-2 thereon. Fig'. 3 is avertical, transverse s ectional view takenv substantially on the line V33 of Fig. 1. And Figs. 4, 5 and 6 are tical side flanges, the latterbeing suitably riveted to the sills 10. Each of said stops is furtherprovided, at its rear end, with a vertical ange -16 to form a stopshoulder Specification of Letters Patent.

with forwardly and rearwardly extended flanges 18-18 riveted to thesills and additional strengthening tapered horizontal flanges 19-19. Therear stop or abutment block 15 is provided with a vertical front face 2Ofor the rear end of the yoke 21 to abut against and with side webs 22-22riveted to the sills, the front wall 20 being suitably braced bv aplurality of horizontally extending webs 23-23- The' yoke 21 is arrangedhorizontally and is guided between the sets of front and intermediatestops, as clearly appears from the drawing. At their front ends, thearms of the yoke` are provided with elongated slots 24 to lreceive thecoupler key 25 by which-the yoke is connected to the draw bar 26, saidkey also extending through elongated 'slots in the sills.

Each of the shock absorbing units, which are arranged in tandem,preferably comprises sets of twin arranged springs 27-257 and followerstherefor. The front shock absorbing unit has the front `follower 17 andthe front intermediate follower.28, the latter being shown more indetail iniFig. 5. As there shown, the follower 28 is recessed at itscenter as indicated at 29 to formed on the front follower 17, to slidetherethrough. The column 30 is concaved on both its upper and lowersurface to thereby form suitable seats for the twin arranged springs27-27- The column 30, as clearly appears from Fig. 4 is larger at itsfront portion as indicated at 31, thereby forming shoulders 82-32adapted to engage the front *intermediate follower 28 at the end of thebufling and draft movements and thus limit the compression of thesprings. It will also be noted that each of the followers 17 and 28 isprovided with suitable bosses 33 on which the springs 27 are mounted.

The rear shock absorbing unit comprises a front intermediate follower 34and a rear follower 35 and twin arranged springs 27- 27, the latterbeing suitably separated by a combined spring spacer and limitin f block36. The two sets of springs and fo lowers ing, a :floating pressuretransmitting blockv are held in proper positionby detachable saddleplates 37 bolted to the lower flanges of the sills, the bolts beinglocked by clips 38.A

In order to operate the gear as a tandem gear under draft, the yoke 21is provided at its center with inwardly extending lugs 39-39, eachhaving a front shoulder 40 adapted to engage the rear face' of thefollower 28 and pull'the latter forwardly under draft. To actuate therear unit under buff- 41 (see Fig. 6) is provided which fits between theintermediate followers 28 and 34 and is engaged by' the rear end of thecolumn 30. The lugs 39 are beveled rearwardly and outwardly asVindicated at 42 and the sides 43 of the block 41 are correspondinglybeveled, as appears from Fig. 2.

In assembling the device, the yoke is slipped in endwise, after whichthe' block 41 is placed in position between the intermediate stops 13and 14.. The shock absorb- Aing units may then be inserted from below,

as is apparent and the draw bar finally inserted and connected to theyoke. The draft gear thus presented is of high capacity in that itcomprises tandem arranged twin sets of springs, the parts may be readilyassembled and disassembled, the stops are so formed and located as topresent the maximum resistance to the strains imposed thereon; and thestops are also relatively small and brace the sills.
